1 Press and hold the ON/OFF button to switch the gauge on.
2 Ensure that the measurement units, dolly size and pull rate are
set as required, see Section 4.
3 Press the start softkey () to begin the test. Load is applied at
the rate defined, displayed numerically on the screen and
illustrated on the load bar.
4 The load continues to increase at the defined rate until either:
a) the dolly pulls off;
b) the gauge maximum pull load / pressure has been
reached (eg. 25MPa for a 20mm dolly)
At this point, the gauge re-winds to ‘zero’ and the user is asked if
they wish to save the reading.
‘---’ indicates a reading outside of range.
If the maximum pull load / pressure has been reached, the gauge will not
re-wind to ‘zero’ until the default hold time of 0.5 seconds has elapsed.
The gauge re-winds to ‘zero’ at a set rate of 1.5MPa/s or equivalent.
5 Pull up the quick connect coupling to release the dolly and
assess the results, see Section 8.
The stop softkey () can be pressed at any time during the test. If
pressed, the user is asked if they wish to save the reading and the
gauge re-winds to ‘zero’. If saved, the “stopped” reading is included in
the statistics.
Dollies can be reused after cleaning until either the top of the dolly
(where it is held in position by the quick connect coupling) is severely
deformed or the dolly surface is no longer flat. Additional dollies are
available from Elcometer or your local supplier - see Section 15.1 -
‘Dollies’ on page en-18 for details.
